A CORPORATION' GF PENNSYLVANIA VJRING-ER Application filed May 1'?,

The present invention is designed to improve Wringers, particularly adapting Wringers of the later types with driving gears, the driving gears being preferably arranged atthe outside of the Stiles. l/Tslhere such gears are provided, particularly with ivringers in which the means are supplied for readily removing the top roll in connection with a detachable top roll it is desirable that the gear may not interfere With the conven` ientremoval of the top roll. lt is also desirable to provide the gears with suitable housings and Where the gear is to be removed it is desirable to supply the housing with a removable top so as not to interfere Withthe removal of the Gear. These features and others are included inthe invention. Other features will appear from the specification and claims.

A preferred embodim n of the invention is illustrated in the accompanying drawings as follows Fig. 1 shows a front elevation of the wringer, partly in section. Y

1 marks the Wringer base, 2 and 2e the stiles, 3 the top roll, 4 the bottom roll, and 5 and 6 the shafts for the top and bottom roll respectively. The side stiles are of sheet metal, box form, and the shafts 5 and 6 extend through a slot 7 which extends through the top of the stiles so as to permit of the easy removal of the shaft The shafts also extend through the outer Wall of one of the stiles and this outer Wall iskprovided with a slot 8 to permit such extension of the shafts, the slot 8 like the slot 7 extending through the top of the stiles. Thewlotver shaft operates in bearings 9 arranged in the side stile and sliding bear- T ing blocks 10 are provided for the upper shaft'also arranged in the stile and removable through the top ot the stile. A spring 1929. Serial No. 363,728.

When the shoulder is turned into register. A n

handle 16 is arranged on the sleeve by means ct which it may be turned. An adjusting screw 17 extends through the sleeve andv is secured to the spring 11. This releasing device is one of common construction and is generally described in the patent to Misner #15,865 (reissue). Y

A .bail 18 is hung on al pin 18a extending across the top bar and extends around a slid-v ing block 10 and the end of the shaft 5, one of these mechanisms being arranged at each end of the cross bar. A latch 19 is also pivotally secured on the pin 18a and has fingers 2O which extend through slots 21 in the inner lWall of the side stile. This latch has a cross plate 22 which is engaged bythe spring 11 when released by the releasing device and when so engaged by the spring the latch is thrown out of engagement With the upper Wall of the slot 21 releasing the top bar so that upon the operation of the safety release a secondary release of the top bar is y effected permitting the detachment of the top bar and if the top bar is lifted the lifting of the top roll through the connection of the bail 18 entirely from the Wringer. This is a desirable feature in that if an operator gets his hand caught the ycomplete removal of the top roll is desirable so as to prevent injury to the hand. This kis par. ticularly truein that it disengages the gear and thus stops the rotation of the top roll.

Gears 23 and 24am fixeduon the `ends of the shafts 5 and 6 and are in mesh, as shown the lower shaft being the drivingfshaft and communicating the movement'to the upper shaft. Y l

These gears are arranged in afhousing. The housing is `formed With a backy plate 25, this back plate being slotted to permit the insertion of the shafts and has lips 26 extending through the slot` 8 in the stile, these lips 26 being bent outwardly and engagmg the inner face of the outer wall of the stile, thus locking the housing on the outer wall of the stile. This manner of forming the lips permits of their insertion into the slot in the stile from the top so that the housing may be merely slipped into place,` and thus assembled. The back plate also has lips 28 struck up on its rear face. These engage the front and rear faces of the stile and make more secure the connection between the baclr plate and the stile. A cover plate 29 is box formed and fits at its open edges the edges of the back plate. Ears 30 are bent from the edges of the cover plate over the rear of the back plate and are spot welded in this position thus completing the assembly.

. It will be noted that the top ofv the housing, so far described', is open and is considerably below the top of the stile. In order that the gear may be readily removed it is desirable that any cover that may be provided for the housing may be removable with the top bar. In the present construction a cover 3l has a lip 32 forming a telescopic connection with the upper edge of the housing. The cover has an upwardly extending projection 33 which extends into the end flange of the top bar and is spot welded on the top bar so that it is carried by the top bar into and out of place. This upward projection 33 is provided with an inwardly struck-up shoulder 34 which engages the edges of the slot 8. The top bar is flange formed and seats over the top of the stiles, thus preventing thel spreading of the stile and the shoulder 3% arranged in the slotV prevents. the inbendingof the top of the stile. It will be understood that the slctting of both the inner and outer walls of the stile'in order to accommodate the shafts 5 and (i weakens very considerably this stile so that this manner of bracing it against collapse, or expansion is of importance.

In the operation of the device, when the release device is operateththe spring first releases the pressure, then engaging the latch releases the top bar, and the operator ordinarily grasps theV top bar with the hand effecting the release, catches the top bar, and removes the wringer roll from the machine. This permits the operator to simply remove, not withdraw, the engaged hand.
